Bain's letter: truth constructed, not reported
he has come to regard the truth as constructed instead of reported. He came by this idea educationally
Context
The epistemology under Orin's register, and Bain's shrewdest stroke. Orin isn't a liar in the ordinary sense; he simply "regard[s] the truth as constructed instead of reported" — a stance he came by educationally, studying "at the feet of the most consummate mind-fucker" (JOI). Truth as a thing you make rather than a thing you find is the exact license irony needs: if nothing is simply the case, then sincerity is only ever another construction, and the man who constructs the most convincing sincerity wins. Bain adds the trap's second jaw: Orin thinks he's escaped his father's influence "through renunciation and hatred," but "Defining yourself in opposition to something is still being anaclitic on that thing" — hatred is still dependence. It's the same diagnosis the book makes of the ironist generally (cf. Day, never refuted, never free): opposition is not escape, and the cynic who has made truth optional is bonded to exactly what he thinks he's rejecting.
